Greed Corp

Destroy the world that feeds you in Greed
Corp, a casual turn-based strategy game that
plays similar to a RTS, but with a twist!

In Greed Corp the player is one of four possible factions fighting over
a hex map with height. The basic idea is to gather resources, construct
fighting units and defeat your enemies. The novel twist is that
extracting resources undermines the land, lowering it in height. If the
height of a hex falls too low, then it collapses - falling away into the
mists along with anything on it, gone forever. In practice this means
forces scurry across the map, leaving devastation in their wake before
engaging the enemy on what little of the map remains. Initially the game
works well.

Unfortunately the game often ends with one side clearly stronger, but
the map denuded of resources. Thus the game descends to a slow grind,
with one side destined for victory, but getting there at a lazy pace
while gathering the scant remaining resources. Later missions in the
campaign also have time limits on turn length, which I personally do not
appreciate (if I wanted such a constraint I’d play a RTS!). Still the
basics are enjoyable enough to keep a player entertained for several
hours.

Greed Corp is out on the Steam
store for PC only at US$9.99.
It has been bundled many times.
